Recent race-related events in Ferguson, Mo., St. Louis, Baltimore, Chicago, Charleston, S.C., and New York City -- all point to the continuing need to study and understand race relations in modern America.

The entire history of the universe for curious minds of all education levels
Astrophysicist and award-winning writer Ethan Siegel recounts the entire development of modern cosmology, including relativity, the expanding universe, stellar nucleosynthesis, the Big Bang, as well as dark matter, dark energy, inflation and baryogenesis in a beautifully illustrated, equation-free book designed to revolutionize astronomy education for experts and non-experts alike.

Cell harm seen in lab tests of e-cigarettes
A lab team at the Veterans Affairs San Diego Healthcare System tested two types of electronic cigarettes and found they damaged cells in ways that could lead to cancer.

Treatment time lags for heart attack patients with prior bypass graft surgery
Heart attack patients who had previously undergone coronary artery bypass graft surgery were less likely than other heart attack patients, including those with prior angioplasty, to be treated within the 90-minute recommended 'door-to-balloon time,' according to a study published today in the JACC: Cardiovascular Interventions.

Myopia-related differences in eye structure may help in developing 'customized' intraocular lenses
The presence of myopia, or nearsightedness, significantly affects the muscles used in focusing the lens of the eye -- a finding with important implications for the development of 'accommodating' implanted intraocular lenses (IOLs) that can adjust to different visual distances, reports a study in the January issue of Optometry and Vision Science, official journal of the American Academy of Optometry.
